From the series of thirty-three prints, Living Endemic Birds of Hawaii, by Marian Berger.
From www.state.hi.us and search: "The Noio or Black Noddy is a medium-sized, abundant, and gregarious tern (Family: Laridae) with a pantropical distribution. Seven Noio (black noddy) subspecies are generally recognized, and two are resident in Hawai‘i: A. s. melanogenys (MHI) and A. s. marcusi (NWHI). Individuals have slender wings, a wedge-shaped tail, and black bill which is slightly decurved. Adult males and females are sooty black with a white cap and have reddish brown legs and feet; bill droops slightly."
The Noio is a seabird from the tern family that measures about one foot in length with a two-foot wingspan. They spend the day at sea feeding, returning to roost on shore at night. Courtship behaviors include head bobbing and exchanging fish between mates. The pair then builds a substantial nest in a cave, tree, or on a rocky ledge, which they will reuse year after year.
